Jorge – Node.js, Typescript, API Gateway

State-driven, curated service marketplace that reimagines how homeowners find and connect with local professionals. The platform replaces the complexity of existing services with an intuitive, corkboard-inspired interface where homeowners “pin” service requests as digital 3x5 cards, and the system orchestrates immediate, curated matches with vetted contractors through a weighted round-robin algorithm and timed response windows

• Led development of an AI agent platform for automatic and manual SQL-driven data retrieval, diagnostics, and predictive inference on trillion-row datasets, built on the TanStack ecosystem.
• Designed a Python-based ELT pipeline (Amazon MWAA, DBT) to ingest raw client data from S3 and transform it into a structured Redshift warehouse for analytics.
• Optimized high-volume SQL queries (Postgres, Kysely) with materialized views, aggregations, and indexing reducing query latency from ~4 minutes to 30-40 seconds (~8x faster).
• Architected and maintained dual cloud infrastructures as code: Serverless Framework (API Gateway, Lambda, S3) for the application layer, and Terraform (MWAA, VPCs, Redshift) for the data pipeline.
• Built and maintained a CI/CD pipeline (GitHub Actions + AWS CodeBuild) tailored to security requirements, supporting continuous delivery for both application and data infrastructure.
• Designed multi-engine database schemas across Postgres, Redshift, and DynamoDB for transactional, analytical, and NoSQL workloads.
• Delivered a full production system using a 100% AI-first development methodology (Claude Code), from architecture to deployment.
• Built an AI-powered intake pipeline (Python, LiteLLM) that classifies user descriptions into service categories with location-calibrated pricing and confidence scoring.
• Designed an event-driven async architecture (EventBridge, SQS with dead-letter queues) orchestrated by AWS Step Functions state machines, automating dispatch, reminders, and follow-ups.
• Owned multi-environment delivery (SST v2, CDK, GitHub Actions) across development, staging, and production.
• Designed a dual-runtime authentication system (better-auth + isolated Cognito pools) supporting Google federation, Twilio phone sign-up, and persona-specific session management.
• Built secure, role-based REST APIs on AWS Lambda across multiple API Gateways, protected by AWS WAF and supporting session-cookie and JWT auth.
• Integrated third-party services end-to-end — Twilio (SMS), AWS SES (email), and Stripe (subscriptions) — powering notifications, billing, and account lifecycle.
• Modeled and evolved the core data layer using PostgreSQL and Prisma ORM.
• Built the frontend and shared design system using Next.js 16 App Router.
• Established observability, testing, and engineering standards — AWS Lambda Powertools logger/tracer with structured-event conventions, CloudWatch dashboards, and SNS alarms.
